I am not aware of any vendors that disputed Vaporshark results besides Cyclops on one juice only.
well you can't forget 5pawns can you? they were VERY upset with the results. VS no longer carries them though.
i'm also pretty sure that cosmic fog disputed one or two. saw it in a blog of theirs.
also, cyclops only made a fuss about one, but ALL the numbers cyclops posted we lower than what VS tests showed (other than the ones that were ND)
i also took it upon myself to email a few of the companies that VS sells, and asked them if their eliquid has D/AP in it (already knowing the answer). some replied "no, none of our eliquids contain diacetyl or ap"......even though according to the VS tests they do.
From the vendors that self publish I find the results of those who show nd across the board more trustworthy, especially if the limits of detection are low ( 1 ppm ). It shows that having diketone free liquids is a company policy and that liquids have been designed with that in mind. There has been internal testing even before 3rd party testing to confirm.
see i look at a company that posts all ND results, and i think it's a little fishy....not more trustworthy.
like really?? you just happened to create all theses liquids and not a single on has any D/AP what-so-ever?
take charlie noble for example. most of the line is D/AP free, but a couple here and there have very low amounts. like 5-12ug or something. that seems a little more trustworthy than "yup we are 100% nd across the board. no discrepancies at all, we made them perfect."
